Good but not great as my business has grown and added complexity.

Not enough flexibility with pay periods. For monthly payrolls in WA state, I'm required to pay the 1st-24th of the month by the end of the month. To have payday be the last day of the month, the pay period sometimes ends on the 24th, sometimes the 25th, and February there is no option to be in compliance as it pays up to the 22nd only.

When an employee maxes their IRA contribution for the year, Gusto stops making employer contributions even though the company is required to pay a % of total income for the year, not only during pay periods in which the employee contributes.

Gusto was not including all reportable earnings to our state family medical leave program. This caused my employee to be denied benefits over her maternity leave. Thankfully she appealed their decision and after I provided payroll reports the PFML program identified the issue with Gusto's reporting and approved her payments. This all took several months though and Gusto still has not contacted my employee to apologize for their error despite me asking them to do so on a couple occasions (and it being the least they could do!)

A few years ago I started the process of having Gusto administer our health insurance benefits. The process was a nightmare and I ultimately decided not to have them do it, however without my signature they had already started changing it over.

Customer service is awful. It's almost not even worth sending an email since it takes months to get a reply and then they often don't address the problem but say "let us know if you need anything else" in which case you will wait another couple months for a reply if you even get one.
